The flexible shaft 22 thus imparts a right-angle drive between the motor I l and said spindle 20.

The gear pump I9 includes an intake fitting 23 and a. discharge fitting 24; the latter being coupled to a hose 25 which leads upwardly in the housing 2 and discharges by means of a nozzle 26 into a horizontal, transversely extending drip trough 21 at the top of said housing.

The drip trough 21 has a plurality of drip openings 28 in the bottom thereof, and said trough is disposed directly above a vertically zig-zag air filter and heat exchange pad 29 disposed in the housing 2 adjacent its rear, end. The pad 29 extends from side to side of said housing and is of a height which leads from within the base pan l upwardly to a point closely adjacent, but short of, the top of said housing; such pad being faced on opposite sides by wire mesh 30, between which is a filler of excelsior 3| or the like. The drip trough 2'! and the filter pad 29 are removably suspendedfrom the top of the housing 2 in the manner shown particularly in Fig. 6, and wherein:

A horizontal, transverse supporting plate 32 is secured close to but spaced from the under side of the top of the housing 2 at a point generally above the normal position of the filter pad 2 9; said supporting plate 32 having downturned front and rear lips 33.

The filter pad 29 has a horizontal, transversely extending attachment plate 34 thereabove in spaced relation; the forward edge of such attachment plate including a downturned lip 35, while the rear edge of said plate is secured by a suspension flange-36 tothe upper portion of the pad, as at 31.

By sliding the attachment plate 34 over the supporting plate 32; i. e. between said latter plate and the top of the housing 2 (see Fig. 3), the filter pad 29 is effectively suspended in place; lip then overlapping the corresponding lip 33 so as to aid in holding flange 34 in place.

Similarly, the drip trough 21 includes, at the top, a horizontal, transverse attachment plate 38 which projects forwardly of said trough and includes a downturned front edge lip 39.

The attachment plate 38 slides over attachment plate 34, between the latter and the top of the housing, for the effective but removable suspension of the drip trough 21 in its proper position of use directly above the uppermost course of the filter pad 29.

The supporting plate 32 has sufficient spring to permit the attachment plates 34 and 39'to engage between the top of the housing 2 and said supporting plate. Such spring also tends to hold the attachment plates 34 and 38 in their engaged positions of use.

Water is prevented from slopping from either end of the base pan l by means of anti-splash flanges F which project inwardly from adjacent the upper edges of said pan above the quantity of water normally disposed in the latter.

When the above described air conditioner is in use, the motor driven fan 9 causes a forceful stream of air to flow through the housing 2, such stream passing through the filter pad 29 in said housing.

During operation of the device the pump 19 is constantly driven -by the flexible shaft 22,

pumping water from within the base pan I upwardly into the drip trough 21, whence said Water drips onto the vertically zig-zag filter pad 29, maintaining the same wet. Additionally, the lower end of said filter pad depends into the water in the base pan l whereby the pad is additionally moistureized by capillary attraction.

As the air stream flows through the filter pad 29 an eifective heat exchange occurs, cooling the air before it is discharged, and further all dust etc. is filtered out of the air as it passes through the pad.

The invention thus provides a very practical, effective, and reliable device for air cleaning and cooling; the device being readily portable from place to place, as conditions may require.

As the pump i9 is mounted on the rearward extension [8 of cross bar l1, and as the motor supporting frame i3 is secured to said cross bar, the working parts of the device are mainly in unitary relation, which permits of ready initial assembly, as well as the subsequent maintenance of said parts in their proper relative positions.

From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended cla ms.

Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:
